To all whom it may concern:

Be it known that I, CHARLES L. 80011, a

ville, in the county of Howard an State of Iowa, have invented a new and useful Block-Machine, of which the following is a specification.

This invention relates to machines of that class employed for manufacturing hniidingi hi blocks 0 concrete or other plastic mater The principal object of the invention isto provide a machineof simple construction which the core members are relatively sta tion and the side and end wails are" an range for connection between the psllet fi that at the com letion of a moldin eperst block carried away to the drying floor, after which the side and end members are moved to release position anddetaeh'ed; allowing the molded block to rest on the anes A further object of the invention is to'protYpe in which provision is made for moving a] of, theside and end walis awa' from the molded block simultane which it engages.

provide a block-molding machine having movable side and endmembers, all of'whic are connected to a sin 1e operating-lever which ma be manipn ated to move said mcml'iers snnultaneonsly to open or to closed position. I A still further object ofthe invention 1s to provide. a machine of this type in which the pallet is of such constrnct'ion as to form a guide for the side and end members of the mold-box during opening and closing movement. V

A still further object of the invention is to provide it machine of this type in which the with detachable moldin plates which may be interchanged with ot l ent construction or of dim-rent contour for the purpose of forming specially-shaped blocks-as, for instance,

10! plates of differcorncr-hlocks r' l' or alter-mg the contou r or face ornamentation A still further obg'ect of the invention is to provide a machine of this type in which the opposite ends of the block may be rovided with recesses formin handholds to ecilitate the'handling of the lock.

X still further object of the invention is to provides novel form of division late to he empllioyed in the manufacture sectional on s.

A still fiirther object of the invention is to lg lidei machine hdYiflgQfll8 members construction as to permit the manufsctnre of e; two-part bloek'ifn which the members are united by transversely-extendbonds in the form of tie-wires or the like. further object of the invention is to iZ 'QYide '9. novel form of core-support which 'wiii' permit independent ad'ustrnent of the cores with relation to each 0t er and will permit the ready interchanging of sets of cores accordance with the character of the block to be made.

With these and other objects in view, as will more fully hereinafter appear; the ininafter fully describe illustrated in the accompanying drawings, and particularly pointed out in the'eppended claims, it being understood that venous changes in the form proportions} size, and minor details of the strnctnre may be made without depsrtin from the s int orsacrificing, any of the ad Vflilti o the inventiiiir.

The sills serve as su ports for a pair of vertically-dis osed stan ards 15, at the up or ends of WhlGh is arranged a table forme of a pair of spaced strips 16. The longitudinal ace or groove between the strips 16 is deslgned for the reception of a bar 17, to the upper face of which are secured two slightly-spaced core-carrying plates 18. The outer edges of the lates are rovided with undercut resesses t at are deslgned to receive the inturned li s 19 of the base members 20 of cores 21. he li s 19 are free to slide on the plates 18, in or er that the cores may be adjusted to any desired position in the length of the plates and to permit the employment of one, two, three, or more cores, in accordance with the character of the block to be made, and the cores may be spaced at equidistant intervals or may be otherwise disposed. To the under side of the central portion of the bar 17 is pivoted a locking-bar 22, which ma be turned at a right angle to the bar 17 an engage with the lower faces of the strips 16 for the pur ose of holding the core-carryingmplates an cores in position. By turning t s bar 22 to a (position parallel with the bar 17 the cores an their carryingplates may be detached as a whole, in order that other Iates and cores may be substituted there or.

Over the cores is placed a allet 25, having 0 enings for the passage oft e cores and provided at both its sides and ends with pro ecting bars 25, the said bars servin as guides for the movement of the side an end walls of the mold-box proper. The mold-box includes two sidewalls 27 and 28 and two end walls 29 and 30, and the upper edge of each of these walls is provided with two or more vertically-disposed studs 30, that are designed to enter suitable openin s formed in the upper flanges 31 of detacha le moldingplates 32, the lower edges of the plates being provided with flanges 33, that extend back to the inner 'face of the mold-walls proper, in order to prevent displacement of the molding-plates during the tam ing of the concrete or other plastic material. These molding-plates 32 are interchangeable, each machine being provided with a large number of sets of plates, in order that the contour of the block may be alteredas, for instance, in the manufacture of corner-blocks or sectional blocksor in order to alter the surface ornamentation of the block, and these moldplates are readily detached, being merely eld by the studs or pins 30, so that one set of plates may be lifted out and another substituted therefor at a moments notice.

The side walls 27 and 28 of the mold-box are provided with depending flan cs 35, that fit between the projections 25 o the pallet, and these projections form guides, so that the side-walls can only move 1n direct lines to ward and away from position, and there will be no danger of injuring the molded faces of the block when the mold-box is opened. In similar manner the end walls 29 and 30 are provided with depending flanges 36, which are also guided by projections 25 of the pallet, but the projections 36 of the end walls also extend under the ends of the pallet-as shown, for instance, in Fi 4so that when the mold-box is closed t e'flan es 36 will serve as sup orts to hold said a et in position above t e table 16 and wil further serve to support the pallet when the mold-box as a whole is raised clear of the cores for the purpose of carryin off a molded block to the drying floor. 'l he side and end walls are also guided to some extent and their outward movement is limited by strips 38, that are secured to the u per ed as of the end walls and project beyon the Si e walls, the ends of said strips bein provided with depending arms 39, which by enga ement with the outer faces of the side wa ls limit the movement thereof. The side walls project for some distance beyond the end walls and are provided with handles 40 41, conveniently ar ranged so that two operators standing on the transverse lanks 11 may grasp the handles and raise tlie mold-box, the pallet, and the finished block clear of the cores. The extended ortions of these side walls are slotted, and through these slots extend levers 43 and 44. The levers 43 are ivoted on pins 45 in the side member 27, and the levers 44 are pivoted on pins 46, carried by the side memer 28. The inner ends of these levers are connected together by a pin 47, and each lever is connected b lmks 48 to the adjacent end wall of the mold-box.

()n the outer face of the side member 28 is secured a bracket 50, the base of the bracket being provided with slots 51 for the passage of securing-bolts, by which it is held to said side member, and the slots permit of any necessary adjustment of the position of the bracket. To the outer end of the bracket is pivoted an operating-lever 52, having a suitable handle 53 at its free end. Adjacent to the pivot or fulcrum point of the lever 52 are two pivot-pins 54 and 55, that are disposed, respectively, on opposite sides of the leverfulcrum. lhv pin 54 is connected by a rod 56 to the outer end of the lever 44, the connection being formed b a sleeve 57, that is pivoted to the outer en of lever 44 and encircles recesses in the en the rod 56, said sleeve being adi'pstable with respect to the rod and being loo ed in its adjusted position by nuts 58. The pivot-pin is connected to the opposite lever 44 in similar manner by a rod 60. In the operation of the device as thus far described the parts are assembled in the position shown in Fi s. 1 and 2, with the parts of the mold-box c osed and a allet in position. The concrete or other p is then filled in and tamped in the usual man nor, the surplus V V levelwith the tops of the cores and the moldbox. Two operators then stand on the transverse lank l7 and grasp the handles fland 41. e moldbox', the pallet, and the molded block are'then raised clear of the cores and carried as a whole to the drying-floor, after which the lever 52 is moved to the 'tion shown in Fig. 3, and this movement is transmitted through the rods 56 and to the and levers and links, the levers 43 and 44 bein moved into alinement with each other an spreading the side members, while 'the links 48 draw the end members away from the molded block, all of the vertical walls of the mold-box movin outward in a direction at a right angle fro %he faces of the block. This separates the hi3? and end walls from the molded block a frees the posltion in a mold, the mold-plates which orm the end air-spaces or bondi d d h -spaces are rovi e wit p of.'the bloc and these recesses afiord handholds, so that the block ma be readily lifted and carried.

t is in many cases desirable to form building-biocks of a sectional character-that is to say, blocks in which the front and rear walls are separated from each other for the purpose of forming continuous air-spaces-so that the wall will remain d and the conduction of heat be minimize For this purpose the core embers maybe of the character shown in Fig. 7that is to say, provided with laterally-projecting tongues 62, which when the'cores are in osition in the mold will be spaced from see other for a distance sufficient to permit the assage of tie-wires or similar bonding mom ers, and eachblock will therefore be formed member's united by metallic bonds and so arranged that the two sections may be handled as one block.

.It is in many cases necessary to form see astic material material being troweled oil 7 pallet, and theblock will be allowed to remain on the pallet ojectionsfi lkwhich form.

of two separate tional blocks, and for this uzpose divisionplates are used. These ivision-plates, as shown in Figs. 2 and 6, are arranged at the ends of arms 66, that extend over the side walls of the mold and have dovmwardly-projeoting portions arranged for the reception of screws 67. By turning the screws and binding the same against the outer face of the mold-box sections the division-plates may be held firmly in place in any position in the jlength of the mold-box, so that sectional blocks of any desired size may be formed.

In Fig. 7 1s illustrated a slight modification ofthe core-support. In this case the plates 18 have their inner edgesprovided with recesses 89 for the rovided with wrench-engaging heads 71. his construction permits oi the adjustment of the core members to any desired position in the length of the core-support, and by turnin the bolts said core members may be firllnlp poked in adjusted position.
